Answer: rrxckz if i knew the answer i would give it to you.
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343

Answer:
I'm not sure but I think the answer is 2187 X^ (14) Y^ ( 42)
Step-by-step explanation:
(3x^2y^6)^7
3^(7) x (X^)^(7) x ( Y ^(6)^(7)
= 2187 X^ 14)Y^( 42)
